Popular Post Goldentaco Posted August 18, 2020 Popular Post Share Posted August 18, 2020 (edited) Searching for exhaust options and needing a USFS spark arrestor I quickly found there is very little information on many of the MFGs websites. With most of the offerings being from European companies, the spark arrestor situation gets even dicier. Finding any information directly from the USFS leads to a bunch of individual tales and questionable interpretations of the actual legalities. The actual legalities lie in a few different documents so lets look at a few of the important designations that play into this big puzzle. I'm not going to wade into interpreting the laws around this as it doesn't really matter what my interpretation is, the LEO you encounter has the final say if a test is conducted. So I decided to compile a list of various Exhausts that do or do not have Spark Arrestors. Those that don't have SA's can be fitted with USFS approved SA's and become legal so long as all the exhaust gasses pass through the SA. As long as the Exhaust outlet is round, this should be easy to remedy. So I set out to make a list of available Exhaust options for the Tenere 700 and sent emails to the MFGs for more information. I will update the list as I get responses. If there are other brands I did not include, leave a comment and I'll update the info. *All the MFG info I am listing is available on their website or was sent to me via an email inquiry I submitted on the website.* A few USFS SA's that may work depending on the Exhaust Outlet I.D.: FMF: This should be 48mm O.D.

Our R&D team is aware of the need for one in the US and we are working on a solution. If/when available, you would simply swap out the existing noise insert for one with a screen on the end (Spark arrestor)." -Arrow - No spark Arrestor currently, but as of 26AUG2020 it is in development. From Arrow: "72626xx silencers all come with a dB-killer: we still have to develop a spark arrester for this bike. Exit pipe internal diameter is 58mm (for silencers with carbon endcap – dB-killer is held in place with a seeger ring) and 43mm (for silencers with stainless steel endcap – the ones with “external” exit pipe)." Extra info: Seeger ring is a brand name for common Snap rings. ---EDIT 13OCT2020--Arrow sales just confirmed they have Spark arrestors available for their Tenere 700 exhausts. The info should be up on their website soon. Very cool they emailed me back specifically with this info based on my previous request. -HP Corse -Has dB killer but NO SPARK ARRESTOR. Per HP Corse sales response, " Our muffler have dB killer and flame breaker." When confirming if Flame breaker is a spark arrestor, "Our mufflers have dB killer not spark arrestor" -Wings - Has a db Killer and Spark arrestor. 48mm outlet. ----Edit: 18AUG2020, Spark Arrestor is USFS compliant but not yet approved.
